For a full-on homemade pizza night, start with my homemade pizza dough and no-cook pizza sauce. Add a fresh arugula salad on the side, and you’ve got yourself one seriously solid dinner.

What Is a Veggie Supreme Pizza?

A veggie supreme pizza is a vegetarian spin on the classic supreme, loaded with a mix of complementary vegetable toppings rather than the usual combination of meat and veggies. This version sticks to the pizzeria favourites: mushrooms, green and red bell peppers, red onion, and black olives, all layered with pizza sauce and plenty of mozzarella.

What Makes It “Supreme”?

“Supreme” is really about the toppings. Instead of featuring just one or two, a supreme pizza brings several together for more flavour and texture in every bite. Here, savory mushrooms, crisp, sweet peppers, sharp red onion, and briny black olives create that loaded supreme feel, no pepperoni or sausage required.

Veggie Supreme Pizza Toppings

ingredients for veggie supreme pizza - pizza dough, pizza sauce, mushrooms, red onion, pepperoncini, black olives, bell pepper, basil, and mozzarella.

The best veggie supreme pizza toppings are the ones that give you a little bit of everything in each bite. For this pizza, that means cremini mushrooms, green and red bell peppers, red onion, and black olives, along with pizza sauce and plenty of mozzarella. It’s a classic combination that feels loaded without turning your crust into a vegetable free-for-all.

The Classic Topping Combination

Cremini mushrooms bring a savoury, earthy bite, while green and red bell peppers add crunch, sweetness, and plenty of colour. Thinly sliced red onion gives the pizza a sharper edge, and black olives bring that salty, briny contrast that just belongs on a supreme.

Add melty mozzarella and your favourite pizza sauce underneath, and you’ve got a solid lineup of vegetable pizza toppings where everything actually works together. Slice the veggies fairly thin so they soften in the oven without weighing down the crust.

Optional Add-Ins

Want to load it up a little more? Homemade sun-dried tomatoes add a punchy pop of rich tomato flavour, while spinach, artichoke hearts, or extra mushrooms can bulk up the veggies. Just resist piling on all the extras at once. A little restraint helps the crust stay crisp and lets those classic supreme toppings shine.

Helpful Tips for the Best Veggie Supreme Pizza

Keep those veggies on the thinner side. Thinly sliced mushrooms, peppers, and red onion have enough time to soften during the short bake without weighing down the crust or staying too crunchy.
Watch the moisture. Mushrooms naturally release water as they cook, so avoid using any that feel especially wet. They go onto this pizza raw, but you can sauté them for 4 to 5 minutes first if yours are particularly moist or you’re worried about ending up with a soggy veggie pizza.
Don’t pile the toppings too high. A loaded veggie pizza is the goal, but there is such a thing as too loaded. An even layer gives the vegetables room to cook and helps the center of the crust crisp up properly.
Give your oven plenty of time to get hot. A properly preheated oven, and pizza stone if you’re using one, gives the dough a head start toward a crisp pizza crust rather than a soft, doughy bottom.
Let the pizza tell you when it’s ready. Look for bubbling, melted mozzarella and a golden brown crust around the edges. Those are much better cues than relying on the timer alone.

Easy Variations

Roasted Vegetable Pizza. Swap the raw veggies for roasted ones when you want deeper, slightly caramelized flavour. Just make sure any roasted vegetables are well drained before adding them since extra moisture can soften the crust.
Vegan Veggie Supreme Pizza. Turn this into a vegan pizza by swapping the mozzarella for your favourite dairy-free pizza cheese. Everything else can stay the same, just double check that your pizza dough and sauce are vegan too.
Extra Cheesy Veggie Lover’s Pizza. For a seriously cheesy veggie lover’s pizza, add an extra handful of mozzarella over the vegetables before baking. You can also replace a portion of the mozzarella with provolone for a little more sharpness while keeping that gooey, loaded veggie pizza feel.

What to Serve With Veggie Supreme Pizza

This loaded veggie pizza is plenty satisfying on its own, but a fresh garden salad, garlic bread, or a few crispy appetizers such as my hot honey ricotta crostini make great additions when you want to round out the meal.

Storage and Reheating

Store leftover veggie pizza in an airtight container in the refrigerator for up to 4 days. If you’re stacking slices, slip a piece of parchment paper between them to keep the toppings where they belong.

For the best leftover crust, reheat slices in a skillet over medium low heat or pop them into a hot oven or air fryer until the cheese is melty and the bottom crisps back up. The microwave works in a pinch, but you’ll lose some of that crispy crust.

Frequently Asked Questions

A classic veggie supreme is loaded with several complementary vegetable toppings rather than just one or two. This recipe uses mushrooms, green and red bell peppers, red onion, and black olives with pizza sauce and mozzarella.

A traditional supreme pizza typically combines vegetables with meat toppings such as pepperoni and sausage. A veggie supreme skips the meat and uses a generous mix of vegetables to get that same loaded, everything-on-it feel.

Mushrooms, bell peppers, onions, and olives are classics because they bring a good balance of savoury, sweet, sharp, and briny flavours. Spinach, artichoke hearts, and sun-dried tomatoes are also great options, just be mindful of excess moisture when adding extra vegetables.

Slice your vegetables thinly, avoid piling on too many toppings, and make sure your oven is fully preheated. Mushrooms can release quite a bit of water, so particularly wet ones can be sautéed for 4 to 5 minutes before topping the pizza, although this is completely optional.

Absolutely. Let refrigerated pizza dough come to room temperature before stretching it so it’s more relaxed and easier to shape. You’ll need about 1 pound of dough for this 14-inch pizza.

Equipment

Ingredients

1 pound pizza dough (homemade or store bought, room temperature)
½ cup pizza sauce
2 cups shredded mozzarella cheese
1 cup cremini mushrooms (thinly sliced)
½ green bell pepper (thinly sliced)
½ red bell pepper (thinly sliced)
¼ medium red onion (thinly sliced)
¼ cup sliced black olives
¼ cup pepperoncini (sliced, optional)

Optional for Serving

red pepper flakes
grated Parmesan cheese
chopped fresh basil

Instructions

Preheat to 475°F (245°C). If using a pizza stone, place it in the oven while it preheats.
Stretch or roll the pizza dough into a 14-inch round. Transfer it to a pizza peel, pizza pan, or greased baking sheet.
Spread the pizza sauce evenly over the dough, leaving about a ½-inch border around the edge. Sprinkle the mozzarella evenly over the sauce.
Top evenly with the mushrooms, green and red bell peppers, red onion, and black olives.
Bake for 12 to 15 minutes, or until the crust is golden brown and the mozzarella is melted and bubbling.

If the cheese or vegetables start browning too quickly before the crust is done, loosely tent the top with foil for the remaining bake time.

Let the pizza rest for 2 to 3 minutes before slicing. Finish with Parmesan, red pepper flakes, or fresh basil, if desired.

Notes

Pizza dough: I love using my homemade pizza dough, but 1 pound of store bought dough works too. Bring it to room temperature first so it stretches more easily.

Pizza sauce: My homemade pizza sauce is my go-to here, but your favourite store bought sauce works in a pinch.

Slice the veggies thin: Mushrooms, peppers, and onion need to be fairly thin so they soften during the short bake and don’t weigh down the crust.

Watch the moisture: The mushrooms go on raw, but if yours are particularly wet, you can sauté them for 4 to 5 minutes first. Don’t overload the pizza with toppings or the center may turn soggy.

For a crisp crust: Make sure the oven is fully preheated before the pizza goes in. If using a pizza stone, let it preheat along with the oven.

Leftovers: Refrigerate in an airtight container for up to 4 days. Reheat in a skillet, hot oven, or air fryer to bring back that crisp bottom.
